A programmable high‐speed true‐time‐delay (TTD) processor using a recirculating loop is proposed for optical beamforming and phased‐array antennas. The number of TTD elements is reduced by several times, in comparison to other methods. The reconfiguration time of beamsteering can reach tens of nanoseconds. The experimental results for the proof‐of‐concept of this optical beamformer are presented. © 2005 Wiley Periodicals, Inc.
